I've never had this on any other Android phones I've owned, but for my Defy it seems the WLAN is on and connected, but it hasn't disconnected the mobile data connection. If I disable and re-enable WLAN, it correctly disconnects mobile data, but within half hour it will reconnect mobile data even though WLAN is still connected! WLAN sleep policy is set to "never".
I appreciate it could be some other setting, or even an installed app that is causing this, so although I'd love to know if anyone knows how to fix this, I'd also love to know how to go about finding the root cause myself (logs, debugging, etc)
